Last week (18th April 2018, Porto), we presented data from some experiments carried out to study the links between microbial diversity and plant and animal (mesofauna, macrofauna) diversity. These experiments are included in Working Package 2 on Biodiversity from the PhytoSUDOE (Interreg) project. We focused our presentation on the links between structural and functional diversity in contaminated and remediated soils. In particular, we presented data obtained in some experimental sites located in Galicia (Spain) and Bordeaux (France), as part of our collaboration with Dr. Petra Kidd (Consejo Superior de Investigaciones Científicas) and Prof. Michel Mench (INRA), respectively.
